Low-cost sensor for cystic fibrosis diagnosis based on citrate

Penn State biomaterials scientists have developed a new, inexpensive method for detecting salt concentrations in sweat or other bodily fluids. The fluorescent sensor, derived from citric acid molecules, is highly sensitive and highly selective for chloride, the key diagnostic marker in cystic fibrosis.
